The TolB protein interacts with the porins of Escherichia coli.
TolB is a periplasmic protein of the cell envelope Tol complex. It is partially membrane associated through an interaction with the outer membrane lipoprotein PAL (peptidoglycan-associated lipoprotein), which also belongs to the Tol system. The interaction of TolB with outer membrane porins of Escherichia coli was investigated with a purified TolB derivative harboring a six-histidine tag. TolB ...
متن کاملMutational analysis of the TolA C-terminal domain of Escherichia coli and genetic evidence for an interaction between TolA and TolB.
The Tol proteins are involved in the outer membrane stability of gram-negative bacteria. The C-terminal domain of TolA was mutagenized to identify residues important for its functions. The isolation of suppressor mutants of tolA mutations in the tolB gene confirmed an interaction between TolAIII and the N-terminal domain of TolB.
متن کاملExpression of proteins using the third domain of the Escherichia coli periplasmic-protein TolA as a fusion partner.
The third domain of the periplasmic protein TolA from Escherichia coli (TolAIII) was used as a fusion partner in the expression of various proteins from bacteria and eukaryotes. TolAIII is small domain, expressed in high yields as a soluble protein in the cytoplasm of E. coli. Proteins were linked to the C-terminus of TolAIII by a short flexible linker containing sites for endopeptidases. Three...
متن کاملEnergy-dependent conformational change in the TolA protein of Escherichia coli involves its N-terminal domain, TolQ, and TolR.
TolQ, TolR, and TolA inner membrane proteins of Escherichia coli are involved in maintaining the stability of the outer membrane. They share homology with the ExbB, ExbD, and TonB proteins, respectively. The last is involved in energy transduction between the inner and the outer membrane, and its conformation has been shown to depend on the presence of the proton motive force (PMF), ExbB, and E...
متن کاملVariation of Intragenic Tandem Repeat Tract of tolA Modulates Escherichia coli Stress Tolerance
In recent work we discovered that the intragenic tandem repeat (TR) region of the tolA gene is highly variable among different Escherichia coli strains. The aim of this study was therefore to investigate the biological function and dynamics of TR variation in E. coli tolA. The biological impact of TR variation was examined by comparing the ability of a set of synthetic tolA variants with in fra...
